Abstract
The utility model relates to a finned evaporator with an obliquely arrayed stacked structure. The problems that condenser pipes of the existing finned evaporators are arranged unreasonably, and the structure strength of fins is poor are solved. The finned evaporator with the obliquely arrayed stacked structure comprises evaporating pipes and a support frame for fixing the evaporating pipes, and is characterized in that obliquely arrayed holes are formed in the support frame; the evaporating pipes are positioned in the obliquely arrayed holes; fins are arranged on the outer surfaces of the evaporating pipes; obliquely arrayed holes are formed in the fins; and flow assisting grooves are formed in the peripheries of the obliquely arrayed holes of the fins. The structure strength of the fins is high; the air on the surface of the evaporator flows smoothly when the evaporator works; and a frost water flowing channel is enlarged, so that the flowing speed of defrosting water is increased, the defrosting speed is increased, the blockage phenomenon of the defrosting water is avoided, and the heat exchange efficiency of the evaporator is improved.
Description
Technical field
The utility model relates to vaporizer technology field, especially a kind of evaporator fin of oblique row's stepped construction.
Background technology
Evaporimeter is important parts of the product refrigeration such as refrigerator, it utilizes the under low pressure easily evaporation of liquid low-temperature refrigerant, change steam into and also absorb the heat of the medium that is cooled, reach the object of refrigerating, its material, structures shape the heat exchange efficiency of evaporimeter, affect the efficiency rank of the products such as refrigerator.Existing evaporation structure abundant species, different use occasions has different designs, also respectively has in detail feature and weak point.If patent publication No. is a kind of evaporator fin that CN101718481A proposes, comprise that some row's fins and some rows are through the condenser pipe of fin, feature is that the length of the floor projection of some row's condenser pipes from top to down increases progressively.And patent announcement number is CN202630520U, disclosed a kind of evaporator fin, comprises aluminum pipe and aluminium fin, is arranged with in turn the aluminium fin that length size does not wait on aluminum pipe.The characteristic point of these two kinds of evaporimeters is not finned length not etc., and the arrangement architecture of condenser pipe there is no optimal way, and fin self insufficient strength.
Summary of the invention
The purpose of this utility model is in order to solve in existing evaporator fin, condenser pipe is arranged unreasonable, the problem of fin structure intensity difference, provides a kind of reasonable in design, has the evaporator fin of the stronger fin strength oblique row stepped construction mobile with being beneficial to surface atmosphere.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the evaporator fin of tiltedly arranging stepped construction, comprise evaporation tube, the fixing bracing frame of evaporation tube, it is characterized in that described bracing frame is provided with oblique round, evaporation tube is positioned in oblique round, evaporation tube outer surface is provided with fin, in described fin, be provided with oblique round, fin is provided with and helps chute at oblique round periphery.Tiltedly round is elongated hole, and evaporation tube is made flat pipe and is installed in elongated hole and coordinates with fin, utilizes limited space structure to obtain maximum evaporation working surface.The thickness of fin own is little, and self intensity is low, when being assembled to evaporation tube, is easily out of shape, even if its atmosphere flow effect of surfacing is not good yet, helps the setting of chute not only to strengthen the structural strength of fin self, the smooth and easy stream of atmosphere while being more conducive to evaporator operation.
As preferably, the position that the oblique round of described fin two contacts with evaporation tube is provided with flange, and flange height is 1～2mm.Flange has increased the contact area of fin and evaporation tube, and the rational flange height of fin of sheeting just has best structure and radiating effect.
As preferably, described bracing frame is provided with parallel two, and two support frame structures are identical, and described oblique round is parallel to each other and acutangulates with bracing frame length direction.Two bracing frames form vaporizer body width, and tiltedly round is established two rows or some rows by product is required.
As preferably, described evaporation tube is serpentine configuration.The purpose of design of serpentine configuration is on limited evaporimeter, in degree scope, to obtain the evaporation tube length grown most.
As preferably, described fin comprises some long fins, and long fin is arranged on the start line of evaporation tube serpentine configuration between terminated line.Long fin, along the evaporation tube total length part of coiling, makes to be evenly equipped with fin on all evaporation tubes.
As preferably, described fin comprises middle fin, brachypterism sheet, and middle fin is arranged in part evaporation tube serpentine configuration, and the length of brachypterism sheet is less than the length of middle fin.Long fin, middle fin, brachypterism sheet cooperatively interact, and are closely sleeved on successively the outer surface of evaporation tube, make evaporimeter one side be solid matter cloth, and a side is white-out cloth, the circulation of atmosphere while contributing to evaporator operation.
Effective effect of the present utility model is: fin structure intensity is large, and during evaporator operation, surface atmosphere is mobile smooth and easy, and has increased white water flow channel, accelerating defrosting water flows out, accelerate defrost speed, avoid defrosting water clogging, improved the heat exchanger effectiveness of evaporimeter.

The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Referring to Fig. 1, the evaporator fin of a kind of oblique row's stepped construction of the present embodiment, by snakelike evaporation tube 2, fixedly the bracing frame 1 of evaporation tube and some fins form.
That bracing frame 1 is established is parallel, structure is identical two, on bracing frame 1, establish the oblique round 11 of two rows, as shown in Figure 2, every row establishes 12 elongated holes, this elongated hole coordinates with the cross section of evaporation tube 2, and snakelike evaporation tube 2 is positioned in elongated hole, at evaporation tube 2 outer surfaces, arranges fin, equally, in fin, be provided with the oblique round coordinating with evaporation tube cross section.
As shown in Figure 3, fin comprises long fin 4, middle fin 5, brachypterism sheet 3, and wherein the length of long fin 4 and evaporation tube 2 overall lengths match, and the length of the length of middle fin 5 and evaporation tube 2/2nds three matches, and the length of brachypterism sheet 3 is 1/2nd length of evaporation tube 2.Fin strikes out and helps chute 32 at oblique round periphery, and at the position contacting with evaporation tube 2, establishes the flange 31 of 1mm, as shown in Figure 4.
Due to the tiltedly setting of round 11, the heat exchange surface of evaporation tube 2 is increased, fin help chute 32 not only to contribute to evaporator operation time the flowing of atmosphere, also played the effect of reinforcement simultaneously, in addition, flange 31 has increased the resistance surface of fin and evaporation tube, makes both structures tightr, and total is more firm.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any structure after simple transformation of the present utility model is all belonged to protection domain of the present utility model.
